Default Is this a Spruce staminate cone?

Source is a Colorado Blue Spruce located in Santa Fe.

Is this an expired pollenator cone? I searched all over the internet
but found no example of this type of cone. These are a little longer
than 1cm long not including the spines.

It looks like a Cooley Spruce Gall. They are caused by adelgids.

YES! Thank you, that's it!

It must be that the aphid's saliva produces a quasi-pinecone growth of
the stem, because they look remakabley like cones.
